RUBBlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 609,832, dated August30, 1898.

Application led January 11, 1897. Serial No. 618,785. (No model.) i

.To all whom t may concern:

Be it known that I, JOHN W'. PENCILLE, a citizen of the UnitedStates,residing at Jamestown, in the county of Ohatauqua and State ofNew York, have invented certain new and useful Improvements inRubbing-Machines; and I do declare the following to be a full, clear,and eXact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference heilig had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of this specification.

The object of my invention is to make a strong and durablerubbing-machine and one which can be adapted to all kinds ofcabinetwork, it being quickly` geared to a long or short stroke and toany height, all of 'which will be readily understood from thisspecification and the accompanying drawings, in which- Figure 1 is aside elevation of my rubbingmachine and table. Fig. 2 is a plan view ofbase-plate with tracks for machine thereon. Fig. 3 shows side elevation,partly in section, of improved rubbing-block. Fig. 4 shows detail ofreciprocating frame,

Similar numerals refer to similar parts throughout the several views.

In the drawings, 19 represents a base-plate, which is firmly anchored toa solid foundation by large bolt 55 and nut 56, as shown in Fig. 4. Uponthis plate are the raised tracks 20 2O 2O 20, Figs. 1 and 4, upon whichtravel the wheels 21 21 21 21, turning frame 10 back and forth when alateral motion is desired to reach any part of the article to be rubbed.Resting upon the lower part of frame 10 in boxes 22 is the reciprocatingframe 11, as shown in Figs. 1 and 4. Within the slot 11' is adjusted oneend of pitman 12 by adjusting-nut 12, and the position of this pitmanmay be varied as a longer or shorter stroke is desired, as indicated at12. Universal joint 13 and swivel-joint 14 allowT the machine to turnupon its track while in motion, if desired. Adjustable wrist-pin 14 ismade sufficiently long to allow pitman 12 to clear wheel 16. Slot 15 inwheel 16 allows a change in the length and speed of the stroke. Thuseach end of the pitman may be adjusted and any desired stroke acquired.

, To the upper part of frame 10 is attached movable arm 28, which bymeans of wormgear 30, crank 29, and block 31 regulates the height ofguide-bar 27. Vhen arm 28 is at the desired height, it is firmly securedand the weight andjar taken from ,worm-gear 30 by lock-nut 28', workingin Vslot 30. Block 3l is locked to guide-bar 27 by set-screw 32, andwhen thus secured easily allows the turning of the frame 10 by movingthe rub-block 38 sidewise in either direction.

The upper part of reciprocating frame 11 is made up of block 23, inwhich are set the four upright rods or tubes 24 24 and which are held bycap 23 at their top. These rods or tubes are made, preferably, oftubing, since it is both lighter and stronger. Vithin these tubescarriage or block 25 freely passes up and down, guided byfriction-wheels 26 on each side, guide-bar 27 passing freely back andforth through carriage 25 as frame 11 reciprocates.

Arm 3G, connecting carriage or block 25 to carriage or block 37, is madeadjustable by passing smaller tube 34 within larger tube 33, and thelength is fixed by a clamp at the desired point.

Rub-block 38, Figs. 1 and 3, is made with oval-headed pin 46, working insocket 50 and attaching the rub-block to the carriage 37, block 47fitting to the bottom of this carriage, springs 39 holding block andcarriage together.

50 is a metal plate extending all over the surface of wood block 51 andin its center having the small metal socket 50', and to which thesprings are attached by staples 48 48. I sometimes put in awearing-piece 54, but this is not necessary and is often left o. Underthe wood part 5l I place a strip of rubber 52, which serves the doublepurpose of protecting the wood of the block from being soaked, andconsequently becoming warped and cracked, and it also furnishes a softsurface for the rubbing-felt 53. This soft surface becomes especiallynoticeable when the rubbing-felt wears thin.

In operating the machine the table-top or article to be rubbed isfastened to the top of IOO car 41, which travels back and forth oninclosed wheels on track 43 on frame 42. Applyin g the power to belt 1818 and pulley-block 17, wheel16 is set in motion, the pitmau causingframe 11 to reciprocate and at the same time giving the same motion tothe rub-block, carriages 25 and 37 playing freely back and forth onguide-bar 27 ,-by which guide-bar the operator controls the work beingdone, the rub-block adapting itself on pin 46 to any small inequalitiesin the surface to be rubbed and rubbing all parts equally on account ofthis adaptation.

It will readily be understood that this machine is equally as welladapted for polishing and sandpapering.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is`

1. In rubbing-machines, a stationary base having a frame mountedthereon, an adjustable arm one end of which is mounted in the top ofsaid frame and the other end connected to a guide-bar, a reciprocatingframe mounted at the base of the frame and provided with a long slot andan adjustable wrist, a pitman attached thereto, the opposite end beingconnected to a drive-wheel to give a reciprocating motion to arubbing-block, and a lateral motion to the guide-bar, as shown anddescribed.

2. In rubbing machines, a reciprocating frame, the upper part havingsuitable rods, a head-block mounted therein, friction-guides securedthereto, a guide-bar mounted in the head-block, a sleeve connecting theguidebar to a movable arm mounted in the frame, the arm having ratchetsto connect with a Worm-gear to raise and lower the guide-bar, aset-screw to lock the arm in position, as shown and described.

3. In rubbing-machines, a reciprocating frame mounted in the base of anupright standard or frame that rests on a base-plate securely mountedbelow the line of the machine, having connections with a drive-wheel tomove the reciprocating frame, having guide-rods at the upper end andguide connections through which passes a horizontal guide-rod carrying arubbing-block which is controlled by a guide-rod and sleeve,substantially as shown and described.

4. In rubbing-machines, the base 19 having ways 2O 20, the uprightstandard 10, having wheels to run on the track, a reciprocating standard11, a driving-wheel 16, pitman 12, movable wrist 13, guide-rods 24,adjustingarm 29, mounted in the top of the main standard, guide-rod 27,a rubbing-block mounted thereon, adj listing-sleeve 35, and rod 3G, allcombined and arranged to operate in the manner and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN W. PENCILLE.
